Federal prosecutors seeking the death penalty against the last U.S. embassy bomber to be sentenced made their final, impassioned plea to jurors yesterday: Kill him, before he kills again.

Khalfan Mohamed, one of four followers of terror chief Osama bin Laden who was convicted in May on charges they helped blow up the embassy in Tanzania in 1998, “is a person who kills in cold blood, and would do it again if given the chance,” prosecutor Patrick Fitzgerald told a Manhattan jury.

Mohamed, 27, who ground the TNT for the bomb and provided housing and a car for his fellow terrorists, has such an utter lack of remorse, he committed atrocities even in jail, Fitzgerald said.

In addition to killing 11 men and women in the bombing, Mohamed was one of two prisoners who nearly killed a federal jail guard last year in lower Manhattan. Officer Louis Pepe is permanently brain-damaged after being stabbed in the eye with a sharpened plastic comb in a foiled hostage-taking plot.

“If he is not put to death, he will be sitting there [in prison], ticking like a time bomb, waiting for the next Officer Pepe to come along,” Fitzgerald said of Mohamed.

The jurors deciding Mohamed’s fate have already spared the life of his co-defendant, Mohamed Rashed Al-Owhali, who was more directly involved in the Tanzania bombing.

They said they feared Al-Owhali would become a martyr if he was executed, inspiring still more deaths.
